I have purchased a 1982 B8200 .The guy that I bought it from said that he was pushing snow with it and it ran out of fuel . I have started it on ether ( yes I know big no no ) It ran and sounded great. The fuel pump cam gear and the idler gear teeth are striped. I can turn the fuel pump cam by hand (with the gear) it turns and feels normal. I am trying to figure out why the teeth striped . I'm thinking that the pump for the hydraulics could be the cause??? Has anyone seen this happen before?? Thanks in advance
